After the release of the Galaxy S4, Apple lawyers have been hard at work trying to add new patent infringement claims in its on-going case against Samsung by dragging the new device into this drama.

In a case that started originally with the Galaxy S back in 2010, Apple has finally dragged the newly launched Galaxy S4 into its ongoing patent war against Samsung by claiming that the device infringes on 5 patents owned by Apple. Furthermore, the Cupertino based company is also crying aiming at Google now for infringing upon its 'Unified Search' patent.

FOSS Patents managed to obtain a copy of Apple's motion which clearly highlights the five patents that the Samsung Galaxy S4 infringes upon.

"asynchronous data synchronization amongst devices"

a "system and method for performing an action on a structure in computer-generated data"

"universal interface for retrieval of information in a computer system"

"graphical user interface using historical lists with field classes"

The third and fourth patent covers Apple's Siri and is most probably targeted at Samsung's S-Voice app, but reports suggest that it is aimed at the Google Now service found in the Galaxy S4 (and every other Jelly Bean running device). There is a fifth patent in which Apple prevailed over HTC which claims that Android infringes iOS on an operating system level, targeting pretty much every device running on Android OS. Google Now is also a part of the case as Apple believes it infringes on its 'Unified Search Boxes' patent.

For now, the Galaxy S4 Google Edition is not a part of the patent infringement case, but we don't think it'll be too long until Apple lawyers take a good look at it and add the device to this case. The lawsuit was originally filed in February 2012, and has yet to reach a firm conclusion (or be headed in such a direction).
